The key difference with WPC from SPC assembly is the LVT top and EXPANDED POLYMER core. A veneer of luxury vinyl is layered on top of the Expanded polymer core board and in addition a core underlayment is attached at the base for sound abatement and enhanced comfort underfoot.
WPC Assembly:
Wood Plastic Composite is made from a blend PVC, limestone, foaming agents, inert ingredients.
Laid down in powder form and pressed and heated to expand the polymer.
The core material is waterproof, rigid and dimensionally stable.
Approximately 50/50 PVC & Limestone.
SPC Assembly:
Solid Polymer Core (SPC) is characterized by the solid nature of the core, regardless of material ingredients.
Most SPC labeled products have a similar assembly which includes: Wear Layer, Print Film, Core, Underlayment.
Not all SPC’s are built the same.
If it does not have an expanded polymer core, it is an “SPC”.
